William Thomas "Will" Riker was a 24th century male Human Starfleet officer. Riker served as first officer for Captain Jean-Luc Picard for 15 years on the USS Enterprise-D and USS Enterprise-E before finally accepting his own command with the USS Titan. (TNG: "Encounter at Farpoint"; Star Trek: First Contact; Star Trek Nemesis)
As captain of the Titan, Riker and his wife Deanna Troi had two children: a son named after Riker's ancestor Thaddius, and a daughter named after Troi's deceased sister Kestra. Thad contracted mendaxic neurosclerosis, prompting his family to move to Nepenthe, where Thad eventually died from his condition. The Rikers remained on Nepenthe for the rest of the 24th century.

In the early 25th century, Riker had returned to active duty as he was scheduled to give a speech during Frontier Day. During Captain Vadic's attack on the USS Titan-A, Riker was temporarily placed in command by the Titan-A's commanding officer, Captain Liam Shaw.
